Enamel on Cast Iron

•

Nonabrasive cleaners: Hot water and 
detergent, Fantastic, Formula 409. Rinse 
and dry immediately.

•

Mild abrasive cleaners: Bon Ami® and 
Soft Scrub®.

•

soap-filled steel wool pad.

•

The grates are heavy; use care when lift-
ing. Place on a protected surface.

•

Blisters/ crazing/ chips are common due 
to the extreme temperatures on grate fin-
gers and rapid temperature changes.

•

Acidic and sugar-laden spills deteriorate 
the enamel. Remove soil immediately.

•

Abrasive cleaners, used too vigorously or 
too often can eventually mar the enamel.

Carefully wipe with cotton swab wet with 
water, ammonia or Formula 409®
